Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

CVE-2026-72438 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix writes_pending and barrier reference leaks on discard failures
raid10_make_request() acquires a writes_pending reference with md_write_start() before calling raid10_handle_discard(). Several failure paths in raid10_handle_discard() complete the bio and return without releasing the corresponding reference, causing md_write_end() to be skipped.
Call md_write_end() before returning from these failure paths to keep writes_pending accounting balanced.
Additionally, discard split allocation failures can occur after wait_barrier() succeeds. Those paths return without calling allow_barrier(), leaking the associated barrier reference.
Release the barrier before returning from those paths.
